[0021] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0022] See also Figure 1 - Figure 7 , this embodiment provides a wood board cutting saw.

[0023] The utility model comprises a frame 1 , a cutting saw 2 , a driving roller 31 , and a pressing roller 32 .

[0024] like Figure 3 As shown, the cutting saw 2 includes a cutting bracket 21, a cutting motor 22, a cutting reducer 23, a cutting saw blade 24, a lower dust cover 25, and an upper dust cover 29. The cutting motor 22 and the cutting reducer 23 are installed on the cutting bracket 21, the cutting saw blade 24 is installed on the output shaft of the cutting reducer 23, the cutting motor 22 drives the cutting reducer 23 to rotate through a belt drive, the cutting bracket 21 is slidably arranged on the frame 1 through a guide rail slider mechanism, the lead screw 27 is rotatably arranged on the frame 1, the other end of the lead screw 27 is provided with a hand wheel 26, the lead screw 28 is provided with a nut 28, and the nut 28 is fixed to the cutting bracket 21 by bolts. The lower dust cover 25 is arranged on the cutting bracket 21, covering the lower half of the cutting saw blade 24, and the upper dust cover 29 is arranged on the frame 1 to cover the upper half of the cutting saw blade 24.

[0025] There are three sets of cutting saws 2, all of which are arranged on the frame 1 in the above manner, and their respective positions are adjusted by hand wheels 26. The cutting saws 2 on both sides are used to correct the two sides of the board, and the cutting saw 2 in the middle is used to split the board into two. In this way, a board can be split into two.

[0026] The upper dust hood 29 and the lower dust hood 25 are connected to a dust collector through a pipeline to suck away the wood chips generated during the cutting process to keep the environment clean and tidy.

[0027] The design of the lead screw 27 and the hand wheel 26 makes it very convenient and practical to adjust the distance of the cutting saw 2. The distance position of the cutting saw 2 can be adjusted at any time according to the different sizes of the wooden boards and the different sizes required to be cut, and the applicability is strong.

[0028] like Figure 2 As shown, the driving roller 31 is rotatably disposed on the frame 1, the driving motor 11 is disposed on the frame 1, and the brush roller 12 is rotatably disposed on the frame 1 and is located on the side of the material discharge. The driving motor 11 drives the driving roller 31 and the brush roller 12 to rotate through a sprocket transmission mechanism, as shown in FIG. Figure 4 As shown, the pressure roller 32 is located directly above the driving roller 31, and its two ends are rotatably connected to the slider 33. The slider 33 is slidably arranged on the sliding frame 37, and the sliding frame 37 is fixed on the frame 1. The upper end of the slider 33 is connected to the screw rod 34, and the upper end of the screw rod 34 extends out of the sliding frame 37 and is connected to the fixing nut 36. The spring 35 is installed on the screw rod 34.

[0029] like Figure 1, 2 As shown, the driving roller 31 is at the bottom and the pressure roller 32 is at the top, with a certain gap between them. The gap is reserved for the board to be cut. The driving roller 31 is used to transport the board forward, and the pressure roller is used to provide a certain pressure to press the board against the driving roller 31 and transport the board steadily. The driving roller and the pressure roller form a pair, with one set of driving rollers and pressure rollers on each side of the saw blade, one set for loading before cutting, and the other for unloading after cutting. Figure 1 As shown, the brush roller 12 cleans the wood chips on the cut wooden board.

[0030] like Figure 1 , 5 As shown in Figure 6, in order to prevent the wooden board from bulging in the middle during the cutting process, which causes the problem of unstable cutting, a pressure wheel mechanism 5 is also provided. The pressure wheel mechanism 5 includes a pressure wheel bracket 51, a first fixing bracket 52, a second fixing bracket 53, and a tension spring. The first rotating shaft 41 and the second rotating shaft 42 are rotatably arranged on the frame 1, and the first fixing bracket 52 is sleeved on the second rotating shaft 42. After adjusting the position, the position is fixed by screws. The middle part of the pressure wheel bracket 51 is rotatably connected to the first fixing bracket 52. A pressure wheel 56 is provided at the lower end of the pressure wheel bracket 51, and the second fixing bracket 53 is sleeved on the first rotating shaft 41. After adjusting the position, the position is fixed by screws. One end of the tension spring is connected to the upper end position of the pressure wheel bracket 51, and the other end is connected to the second fixing bracket 53. A baffle plate 54 is provided on the second fixing bracket 52, and an adjusting bolt 55 is threadedly connected to the baffle plate 54. The end of the adjusting bolt 55 presses the pressure wheel bracket 51 tightly.

[0031] like Figure 5 As shown, the pressure wheel 56 is pressed downward by the action of a tension spring (not shown in the figure) to press the wooden board below to prevent the wooden board from rising and falling during cutting. The first rotating shaft and the second rotating shaft can rotate, so the pressure wheel mechanism is flexible and can be used for wooden boards of different thicknesses. Multiple pressure wheel mechanisms can be installed on the first rotating shaft and the second rotating shaft as needed.
